Abstract

This study aims to develop a Holistic Mathematics Education (HME) model based on the Realistic Mathematics Education (RME) approach, specifically designed for upper-grade elementary school students. The study adopts the Plomp development design, which consists of three main phases: (1) the Preliminary Phase, aimed at collecting empirical data to determine the characteristics of the model to be developed; (2) the Development Phase, aimed at designing and developing a valid and practical HME model based on the RME approach through a series of formative evaluations; and (3) the Assessment Phase, aimed at measuring the model's effectiveness in improving conceptual understanding, learning motivation, and students' character values. However, this research focuses solely on the design phase, producing outputs such as a model book, a teacher's guidebook, and a student's guidebook. The research instruments include validation sheets for both the instruments and the products, which were reviewed by experts to ensure their validity and reliability. This validation process ensures that the developed products have a strong theoretical foundation and are practically applicable in teaching mathematics at the upper elementary school level. The findings indicate that the developed products meet the criteria for validity and can thus be used for upper-grade elementary students. In subsequent stages, this model will be implemented with upper-grade students to assess its practicality and effectiveness.

Abstract

This study aims to develop and test the feasibility of interactive media based on Augmented Reality (AR) in Mathematics learning on spatial geometry material in fifth grade elementary schools. The development of this media uses a 4D development model consisting of four stages, namely Define, Design, Develop, and Disseminate. In the Define stage, a needs analysis is conducted through observation and interviews with teachers to identify obstacles in Mathematics learning. The Design stage includes designing the AR media display and compiling spatial geometry materials according to student characteristics. The Develop stage includes the creation and validation of the media by material experts, language experts, and media experts, which resulted in validation scores of 96.42%, 93.75%, and 95.83%, respectively, with a very valid category. The Disseminate stage was conducted through trials at SDN 10 Koto Tinggi Surian and SDN 08 Tambang Surian to measure the practicality and effectiveness of the media. The results of the practicality test showed a student response of 91.67% and a teacher response of 94.15%, with a very practical category. Meanwhile, the results of the effectiveness test using the N-Gain Score analysis showed a significant improvement in student learning outcomes, with an average score of 0.74 at SDN 10 Koto Tinggi Surian and 0.71 at SDN 08 Tambang Surian, which are in the high category. Thus, the AR-based interactive media developed using the 4D model has proven valid, practical, and effective in improving understanding of spatial concepts and supporting the implementation of the Independent Curriculum.
